WILLIAM TRAPP, JR., OF DRYDEN, NEW YORK.

BARREL MACHINERY.

Specification `forruiing part of Letters Patent No. 4,218, dated October 1, 1845; Reissued March 10, 1849, No. 132.

T0 all 'wh-0m t may concern Be it known that I, WILLIAM TRArP, Jr., of Dryden, in thecounty of Tompkins and State of New York, have invented a new and .useful Improvement in the Construction of Machinery for the Manufacture of Firkins and other ilge-Work; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings of the same making part of this specification, in which- Figure l is an isometrical perspective view of all the machinery employed in the manufacture of the irkin, or other similar cask. Fig. 3 represents a front and edge view of the crozing tool, stock, and changeable face plate. Fig. 4C is a front or face of the tool for turning off theoutside of the cask, after it isplaced on the mandrel. AFig. 6 is a horizontal section of the ways, slide rest, &c., for supporting and maving the last mentioned tool in a direction to conform with the bilge of the cask. Fig. 7 is a vertical cross section of ditto. Fig. 8 is a side view of the chamfering tool, inverted. Fig. 9 is a side view of the howeling tool.

The frame A is made of sufficient capacity and strength to contain and support the several parts to be hereafter described.

After the staves have been sprung, edged, and jointed in a swing frame, or in the most approved Ymanner, 'they are set up in the form ofa firkin and placed between two circular metallic heads f f attached to a mandrel e, and secured to said heads by points, projecting therefrom,` entering the staves. The mandrel is then placed in its bearings, as shown at D in Fig. 1, and is revolved by a band R leading from a pulley H on a shaft S2 to a pulley J on the mandrel-motion being given to the shaft S2 by a band M leading from a drum z under the table. In front `of the cask thus connected with the mandrel are arranged two' parallel straight bars g g Figs. l, 6 and 7, that serve as ways for a sliding rest 7c to i` travel on, being firmly joined together at each end, and bolted to the frame at one end by a single bolt W2, Fig. 6 on which they vibrate; andl resting on ways or rails W. Between these bars is arranged a screw L resting in boxes secured to the piecesco-n'- necting the extremities of the bars g tof gether, and turned by a band vl leading from a pulley T on the mandrel e to a pulley U on the end of the screw h. A slide rest 7c is placed between these bars g g resting on the edges of t-he same, which is moved past the Cask over said bars, by means of a divided nut X Fig. 7 resting on the screw of the ordinary construction and arrangement so as to be detached therefrom at the will of the operator. Upon the slide rest are erected two vertical standards 7c 7a2 with a cap piece K at top, having an oblong opening formed in it for the insertionof a tool and stock L between the said standards, the handle L4 of said tool extending up through said opening in the cap K for the operator to lay hold of and the lower end having an opening in it, into which is inserted a pin P projecting from the upper surface of the slide rest 7a, upon which the tool rests and turns. This tool has its inner face represented at Z, Z,`Z2 Figs. 4 and 7 and is composed of a block of wood L, in which is inserted a cutter Z', the edge and face of which extends the full distance across the face of the stock, at right angles to the shanks Z3 Fig. 7, which are inclined and recessed into the sides of the stock and keyed after the manner of a plane, for holding the tool or cutter firmly in the position. Immediately above this cutter there is a gage or movable face plate Z2, that is kept close to the edge of the cutter Z so as to form the throat of the tool, and gage the thickness of shaving to be taken off. The pin l? on which the tool stock rests, holds the lower end of the stock in the required position, and allows the upper part L4 to turn and move toward or from the mandrel, being guided by the slit in the cap K by this means the tool can i along with the rest r, the ends of the ways g neXt the pattern m is carried out and in, following the curve n, which brings the tool into proper relative position with the work, its movement correspondingwith the bilge of the cask. This pin N is shown by dotted lines at N in Fig. 6. It has an antifriction roller on it for reducing the friction between f the rubbing surfaces. There is a similar pin N2 on the under side of the rest 7c on which there is also an antifriction roller for traveling along in the curved slit n of the pattern m for guiding the tooth, .as represented at N2 in Fig. 7 and by dotted lines in Fig. 6.

After the cask I or firkin (as set up) has been turned off on the outside as described, it is transferred to a hollow cylinder E turning in collars Q attached to the bench, one at each end, and secured firmly therein `by two chucks or annular bar wedges O made to iit the taper of the cask and inserted in the ends of the cylinder E between it and the cask II one being fixed stat-ionary at one end of the cylinder, and the other formed to slide in and out between the cylinder .and cask. AThe firkin is placed in this cylinder with its ends projecting beyond it, and the circular wedge O is forced between it and the inner periphery of the cylinder, holding it firmly in its position. It is then put in motion by bands 00,1% leading from the driving drum a and passing around intermediate pulleys, and around the hollow cylinder. The wedge or chuck 0, in Fig. 1 above named is divided on one side and has two staples 02 driven into its end on opposite.

sides for drawing it out when required; by being divided it can bedriven 1n tight, and made to bind equally on the cylinder and cask. The tools for howeling and chamfer-A ing are lthen applied. These tools are shown at F and Gr, and the one for chamfering consists of a straight bar g? having a foot or rest g .projecting from it at right angles, at one end, at which end the cutter r is afiXed; this tool Ais applied as represented at F Fig. 1. The knife being in contact with the edge of the cask and the foot g resting on the bench, serving to hold the tool in a firm position during the operation; being also preventedl from moving laterally by a hook 's fastened to a standard in the bench and brought down over the inner end. The outer end of the bar is gradually raised during the operation, causing the knife to lower and cut the chime, till said outer end of the bar- .comes in contact with a projection formed don a hinged gage bar z5 attached to the frame .for .the tool during the operation of howeling made i-n a similar manner `to those of the chamfering tool. The blade is also composed of a piece of cast steel forming a segment blade with two cutting edges and a straight shank to be inserted into the handle; but its cutting edges are below the upper surface of the handle as represented at r2 in Fig. 9, so as to be in a proper position for performing the lrequired operation of howeling the cask without the necessity of changing the apparatus (si, t) for holding and gaging `the tool as described.

The cro-zing tool V for cutting the croze is formed 'in the usual manner, eXcept in the particular of constructing the stock 'w3 so that the face .plate `can be changed from one side to the other so as to make the crozing tool work at either end of the cask. For this purpose the stock ua is made alike on'both faces, as represented at 'as Fig. 3 having dovetailed grooves u cut in it to admit corresponding dovetailed ribs u formed 'on the face plate w, by which construction the crozing tool can be applied at either end of the c zsk .by simply turning the stock on the .face

ate.

What I claim -as my invention and desire to secure by Letters Patent is 1. The combination of the slide rest 7c guided in the manner set forth, with the tool L for turning off the cask, constructed and arranged in the manner set forth.

2. I also claim the apparatus for chamfering and howelingand crozing, that is to say the combination of the cylinder E open at both ends, so that both ends of the cask can be wo-rked of without changing, with the chucks O for fastening the cask into the cylinder and with the tools as herein described for chamfering and howeling.

3. I also claim the crozing 4tool V with the changeable face vplate fw as herein set vdescribed and represented in Fig. 4.

5. I likewise claim the peculiar construction of lthe tool for howeling the cask as fabove described and represented at Fig. 9.

v6; I likewise claim the peculiar construction of the tool for chamfering vthe ends of vthe cask as above described and represented in Fig. 8.
